Works well with others
As a senior level employee it's my job to train and mentor new employees. I hold workshops to assist other disciplines. I'm involved in the hiring process and conduct interviews.
Frontend and fullstack developers are intermediaries and great collaborators. We bridge and align stakeholders, engineers, designers, customers, end-users, and others.
My experience ranges from a lone wolf responsible for everything to large teams with over 1,000 people, both in person and remotely.
